WILLIAM EDGAR JOHN, OF PHILADELPHIA, YENNSYLVANIA, ASSIGNOR TO HALLWHEEL CGRPOIL-ATION,` 0F PHILADELPHIA, PENNSYLVANIA.

RESILIENT RING ANI) METHOD OF MAKING SAME.

Application filed November 26, 1923. Serial No. 676,886.

` To all whom t may concern:

`Be it known that I, WILLIAM EDGAR Jol-IN, a citizen of the UnitedStates, residing at Philadelphia, in the county of Philadelphia `andState of Pennsylvania, have invented certain new and useful Improvementsin Resilient Rings `and Methods of Making Same, of whichthe following isa specification. j

My invention relates to resilient rings.

vention are especially adapted is for making a yielding connectionbetween the disks and the rims of disk wheels and I have illustrated thering as applied tosuch use.

` One object of my invention is to provide a resilient ring whichincludes a net work of threads or cords so disposed and supported thatstresses, upon the ring such as those induced by shocks imparted to thevehicle wheels or due to starting and stopping the vehicle, will beuniformly distributed upon the threads or cords throughout their length.Another object is to provide a simple and economical method ofmanufacturing such rings.

In the drawings,

Figure l is a side view of a disk wheel having my invention appliedthereto,

Figure 2 an enlarged fragmentary section on the line 22 of Figure l,

Figure 3 `a fragmentary side view, partly in section, of a resilientring constructed in accordance with my invention,

Figure 4 a face view of a former which may be used in constructing thering,` the former being shown on an enlarged `scale relatively to thering,

Figure 5 a section on the line 5-5 of Figure 4;, and

Figure 6 a section on line 6-6 of Figure 3.

Referring to the drawings, 1 indicates the disks, 2 the rim and 3 myimproved resilient ring which is shown as secured to the disks by rivets4 and to the rim by rivets 5. The resilient ring is preferablyconstructed upon a former having a suitable base 6 and provided with aseries of pins 4 corresponding in position to rivets 4 and anotherseries of pins 5 corresponding in position to rivets 5. The former ispreferably adapted to serve as the lower flask of a mold. Assuming thatthe pins 4 and 58L project horizontally, and that a cord 7 starts from apin 5a, the cord is reeled `on the pins, Zig-zag fashion, in thefollowing;` manner. It is first passed under a diagonally adjacent pin4a, then over the next diagonally adjacent pin 5a, under the nextdiagonally adjacent pin 4 and so on until the circuit is completed. Inother words it is passed under alternate pins in the inner series ofpins and :over alternate pins in the outer series. Another cord 8 isthen attached to the pins 4 which .is opposite the pin 5a, which. wasthe starting point for the first winding, and is passed over adiagonally adjacent pin 5, under the next diagonally adjacent pin 4a andso on until the circuit is completed. It will be noted that this cordpasses over and under the alternate pins in each series which wereskipped in the first winding. A third cord, 9, is then attached to oneof the pins 5, but, instead of passing under the diagonally adjacent pinin the other series, it is passed under the next pin in that series andover the second adjacent pin in the other series and so on until thecircuitJ is completed. A fourth cord, 10, is then attached to the pin4a, opposite the pin 5"n1 from which the third cord started, and isreeled in the same manner until the circuit is completed. These windingsare repeated until the mass is sufficient to form the ring. A Eller ofany suitable composition is then poured into the mold and molded aboutthe cords. suiicient pressure being applied to form a compact ring ofthe desired thickness. When the ring is removed from the mold the holesleft by the pins serve as rivet holes for securing the ring to the disksand rim of a wheel.

If the total number of rivets and of the corresponding pins in the moldbe an odd number the windings may be made from a single cord inasmuchas, when the first circuit is completed, the cord will pass to .a pinwhich was skipped in the first circuit and the windings may be completedby a single cord.

It is obvious that the windings may be varied and the series of windingsabove described is to be taken as indicating a preferred form.

Except when otherwise indicated I use the term cord as indicating anykind of a strand, fibrous or metallic, which has the needed strength andresiliency. v o

A ring constructed as above described w111 absorb the shocks impartedbyl the vehicle Wheel and the torsional'stresses due to starting andstopping the vehicle' will be uniformly distributed upon the cord orcords.

1While I have described my invention as taking a particular form, itAwill be under-v stood that the various parts may be changed withoutdeparting from the spirit thereof, and hence l do not limit myself tothe precise construction set forth, but consider that l ani at libertyto make such changes and alterations as fairly come Within the scope ofthe appended claims.

Having thus described my invention, What I claim as new and desire to.secure by Letters Patent is l. The herein described method ofconstructing resilient rings consisting in reeling a cord or cords aboutan outer and an inner series of pins, the cords passing successivelyfrom a pin in. one series to a pin inthe other series; adding'a iiller,and molding the filler about the cords and pins.

2. The herein described method of constructing resilient ringsconsisting in reeling a cord or cords about an kouter and an innerseries of pins, the cords passing suocessively from a pinyin one seriesto the next diagonally adjacent pin in the other series then, in thesame Way, from a pin skipped in the rst circuit to the otherpinsrslripped in that circuit, then from a. pin in one series to anon-adjacent pin in the other series; adding a iillerand molding thefiller about the cords and pins.

3. A resilient ring consisting of a cord or cords and a ller moldedthereabout, the ring including an outer and an inner series of rivetholes andthe cord, or cords being so reeledY that they pass successivelyover a rivet hole in one series and under a rivet hole in the otherseries.

el. A resilient ring consisting of a librous cord or cords and a lillermolded thereabout, the ring including an outer andl an inner series ofrivet holes and the cord or cords being so reeled. that they passsuccessively over a rivet hole in one series and under a rivet holentheother series..

In testimony whereof I have signed my name to this specification.

VVILLIAhlA EDGAR JOHN.
